“How does a bear behave when encounter a human? In most cases he runs away. But before running he almost always would rise to stand on his rear feet. And this behavior does not indicate the attack, as many people think.

On a rare occasion a bear might start an attack on human after getting up on rear feet. But for the actual attack he will get back on all fours anyway.

It is an amazing experience to see a bear standing up on his rear feet: animal resemblance with humans is phenomenal. The head of this large mammal is usually raised over 6.5 feet above the ground at these moments.
